Bulked up to 240 now I want to cut to 200 :ugh:

I'm 6'1 240 at about 19-20% BF, I want to now cut to 200, I've been bulking for a WHILE. I want to do this quickly as to be cut for a portion of the summer, but without losing a majority of my muscle. Any advice?

1- find maintenance then drop by 750-500 cals
2- do fasted cardio first thing in AM post fat burners (low intensity for 30-45 mins, build to 60 mins then break it up into 2, 30 min sessions, in AM and PM and build them to 50 mins each)
3- do HIIT on off days 2-3x per week (uphill)
4- keep the same weightlifting program that got you the muscle (but don't go as heavy when you start to get weaker, you want to avoid injuries. At this point increase the rep range and add more sets all depending on your body/where your at)
5- do the palumbo diet (don't do HIIT on 0 carb days though, only on carb days)
